8700: If one enables Secure Boot on Win 10 with the original GT 635 video card, what would happen?

Recently installed Windows 10 v. 1903 on XPS 8700 which has video card GeForce GT 635 (I think is non-UEFI card). Currently these are my boot settings:

BIOS A14
Boot mode: UEFI
Legacy OPROM: Enabled
Secure boot: Disabled.

What would happen if I were to enable Secure Boot? Since that automatically disables Legacy OPROM, would the video card no longer function? i.e., would I lose all graphics?

Thanks for comments.

Non UEFI cards DO NOT DISPLAY or Load or work with secure boot ON.

When installing an after-market graphics card with UEFI secure boot enabled, the system may not post.
